DESCRIPCIONDESCRIPTION
Un sistema de proteccion antirrobo electronicoAn electronic anti-theft protection system
La invencion se refiere a un sistema electronico para la proteccion antirrobo de productos, comprendiendo dicho sistema: una unidad para detectar el material metalico en una zona de deteccion; una unidad para detectar un material magnetico o magnetizable en una zona de deteccion; y una unidad de control.The invention relates to an electronic system for the anti-theft protection of products, said system comprising: a unit for detecting metallic material in a detection zone; a unit for detecting a magnetic or magnetizable material in a detection zone; and a control unit.
Hoy en dfa, la proteccion antirrobo de productos en, por ejemplo, tiendas o supermercados se logra, en gran medida, colocando una alarma en los productos individuales. Los sistemas conocidos para prevenir el robo suelen comprender las denominadas alarmas antirrobo que se fijan a los productos de las tiendas.Today, anti-theft protection of products in, for example, stores or supermarkets is achieved, to a large extent, by placing an alarm on individual products. Known systems to prevent theft usually include so-called burglar alarms that are set for store products.
En las tiendas de ropa, la proteccion antirrobo esta constituida habitualmente por una alarma antirrobo de dos partes, en la que una parte comprende una tachuela que se inserta a traves del artfculo de ropa y se bloquea en la otra parte de la proteccion antirrobo. Asf mismo, la alarma antirrobo contiene una unidad que puede ser detectada por un mecanismo antirrobo situado en la salida de la tienda. El bloqueo de la alarma antirrobo se libera mediante un iman, que es el denominado liberador, y la liberacion esta destinada a tener lugar en la caja registradora, despues de la compra del artfculo de ropa.In clothing stores, the anti-theft protection is usually constituted by a two-part anti-theft alarm, in which one part comprises a tack that is inserted through the article of clothing and is locked in the other part of the anti-theft protection. Likewise, the burglar alarm contains a unit that can be detected by an anti-theft mechanism located at the exit of the store. The blocking of the burglar alarm is released by a magnet, which is called the release, and the release is intended to take place at the cash register, after the purchase of the article of clothing.
No obstante, actualmente existe el problema de que los ladrones de tiendas traen su propio iman/liberador y, mediante el mismo, quitan la alarma antirrobo, con la consecuencia de que el mecanismo antirrobo es incapaz de detectar el artfculo robado cuando el artfculo pasa por el mecanismo antirrobo. Esto suele ocurrir en las zonas de las tiendas donde, por decencia, los clientes no son vigilados visualmente, por ejemplo, en probadores o banos publicos.However, there is currently the problem that shop thieves bring their own magnet / release and, through it, remove the burglar alarm, with the consequence that the anti-theft mechanism is unable to detect the stolen item when the item passes through the anti-theft mechanism This usually occurs in store areas where, by decency, customers are not visually monitored, for example, in fitting rooms or public bathrooms.
La proteccion de los productos frente al robo tambien puede lograrse mediante, por ejemplo, una espiral, un iman o un pequeno radiotransmisor albergados en pegatinas colocadas sobre los productos y que tienen la capacidad particular de contener informacion, sin batena, que se libera cuando pasa por un campo magnetico o se expone a una senal de radio. Poniendo una alarma en cada artfculo individual, por ejemplo, en un supermercado con este tipo de proteccion antirrobo, tambien es posible registrar si los productos por los que no se ha pagado pasan por puntos seleccionados. Esto suele hacerse en las cajas registradoras o en las salidas como tal, de las tiendas.The protection of the products against theft can also be achieved by, for example, a spiral, a magnet or a small radio transmitter housed in stickers placed on the products and that have the particular ability to contain information, without batting, that is released when it passes by a magnetic field or exposed to a radio signal. By setting an alarm on each individual item, for example, in a supermarket with this type of anti-theft protection, it is also possible to record if the products for which it has not been paid go through selected points. This is usually done at cash registers or at exits as such, in stores.
No obstante, los ladrones profesionales son conscientes de que tales protecciones antirrobo electronicas pueden eludirse protegiendo los productos robados del entorno mediante un escudo contra radiacion, la denominada "jaula de Faraday" que elimina toda la influencia electrica del exterior o desde el interior. Normalmente, esto suele realizarse de manera bastante sencilla aislando, por ejemplo, una bolsa o una mochila/bolso, con una capa interior de material conductor, tal como, por ejemplo, papel de aluminio, aunque, en principio, puede utilizarse cualquier material conductor. Tal receptaculo aislado impide de manera eficaz cualquier deteccion de los productos con alarma contenidos en su interior y, por lo tanto, tambien impide que se descubra cualquier producto robado que pueda estar presente en el recipiente aislado; asf, tales receptaculos aislados, denominados en terminos coloquiales "booster bags" en ingles o "bolsas reforzadas", tambien son la causa directa de una perdida considerable de productos en el sector al por menor.However, professional thieves are aware that such electronic anti-theft protections can be avoided by protecting stolen products from the environment by means of a radiation shield, the so-called "Faraday cage" that eliminates all electrical influence from outside or from inside. Normally, this is usually done quite simply by isolating, for example, a bag or a backpack / bag, with an inner layer of conductive material, such as, for example, aluminum foil, although, in principle, any conductive material can be used . Such an isolated receptacle effectively prevents any detection of the alarm products contained therein and, therefore, also prevents the discovery of any stolen product that may be present in the insulated container; thus, such isolated receptacles, denominated in colloquial terms "booster bags" in English or "reinforced bags", are also the direct cause of a considerable loss of products in the retail sector.
Por lo tanto, hoy en dfa se han introducido detectores de metales que son capaces de detectar tales "bolsas reforzadas" y, actualmente, una proteccion eficaz antirrobo de los bienes consiste en utilizar, tanto sensores para detectar las senales que emiten los productos con las alarmas, como detectores de metales para detectar las "bolsas reforzadas".Therefore, today metal detectors have been introduced that are capable of detecting such "reinforced bags" and, at present, an effective anti-theft protection of goods consists in using both sensors to detect the signals emitted by the products with the alarms, such as metal detectors to detect "reinforced bags".
Los detectores de metales son muy conocidos por los expertos en la materia y pueden fabricarse, por ejemplo, tal y como se describe en los documentos US 6.133.829, JP 8 050 690 o EP 0 736 850 y, por lo tanto, no se describiran sus funcionalidades con mas detalle.Metal detectors are well known to those skilled in the art and can be manufactured, for example, as described in US 6,133,829, JP 8 050 690 or EP 0 736 850 and, therefore, are not They will describe their functionalities in more detail.
Los detectores de imanes tambien son muy conocidos por los expertos en la materia y pueden fabricarse, por ejemplo, tal y como se describe en el documento US 3.971.983.Magnet detectors are also well known to those skilled in the art and can be manufactured, for example, as described in US 3,971,983.
No obstante, los carros normales de acero constituyen un problema, pues tambien son detectados por los detectores de metal, por lo que emiten "falsas alarmas" cada vez que un carro de acero pasa por un detector de metal.However, normal steel cars are a problem, as they are also detected by metal detectors, so they emit "false alarms" every time a steel car goes through a metal detector.
Por lo tanto, existe la necesidad de disponer de un sistema que minimice los inconvenientes anteriores.Therefore, there is a need for a system that minimizes the above inconveniences.
Esto se logra con la unidad de control segun la reivindicacion 1.This is achieved with the control unit according to claim 1.
Por la presente, se logra un sistema de proteccion antirrobo mejorado que puede prevenir falsas alarmas.Hereby, an improved anti-theft protection system that can prevent false alarms is achieved.
Las realizaciones de la invencion se proporcionaran en las reivindicaciones independientes.Embodiments of the invention will be provided in the independent claims.
Ha de interpretarse que el termino "material metalico" comprende medios que normalmente se consideranIt is to be interpreted that the term "metallic material" comprises means that are normally considered

magneticos, incluyendo, pero no limitandose a, por ejemplo, papel de aluminio, aluminio, acero inoxidable austemtico u oro y plata. Dichos materiales pueden ser detectados por detectores de metal, pero no por detectores que detectan materiales magneticos/magnetizables. Por materiales magneticos ha de entenderse materiales que pueden magnetizarse, incluyendo el hierro (Fe), el mquel (Ni) y el cobalto (Co).magnetic, including, but not limited to, for example, foil, aluminum, austemotic stainless steel or gold and silver. Such materials can be detected by metal detectors, but not by detectors that detect magnetic / magnetizable materials. Magnetic materials are understood as materials that can be magnetized, including iron (Fe), nickel (Ni) and cobalt (Co).
Los terminos "dispositivo de deteccion, sensor o detector" han de interpretarse como aparatos electronicos que pueden, en situaciones determinadas, proporcionar desviaciones cuando detectan/miden los objetos magneticos o metalicos en un volumen/area determinada que puede, por consiguiente, designarse como la zona de deteccion y/o area de deteccion/medicion.The terms "detection device, sensor or detector" are to be interpreted as electronic devices that can, in certain situations, provide deviations when they detect / measure magnetic or metal objects in a given volume / area that can, therefore, be designated as the detection zone and / or detection / measurement area.
La programacion no ha de interpretarse como algo que este necesariamente relacionado con el soporte logico; en su lugar, tambien puede significar el movimiento de los cables en una serie de interruptores.Programming should not be interpreted as something that is necessarily related to software; instead, it can also mean the movement of the wires in a series of switches.
A continuacion, se explicara una realizacion de la invencion con referencia a las figuras, en las queNext, an embodiment of the invention will be explained with reference to the figures, in which

las figuras 5A-5D muestran esquematicamente como un cliente que lleva una mochila pasa por una realizacion de un sistema segun la invencion.Figures 5A-5D schematically show how a customer carrying a backpack goes through an embodiment of a system according to the invention.
La figura 1 muestra un dibujo del campo magnetico de la Tierra conforme discurre entre el Polo Norte y el Polo Sur, y la invencion contiene un sensor que registra los cambios en el mismo. Tales sensores se conocen y se utilizan hoy en dfa en una version capaz de medir los cambios en el campo magnetico en tres dimensiones, por ejemplo, para brujulas electronicas y su uso en aviones, telefonos moviles, mediciones de corriente en un cable, o para la deteccion del trafico.Figure 1 shows a drawing of the Earth's magnetic field as it runs between the North Pole and the South Pole, and the invention contains a sensor that records changes in it. Such sensors are known and used today in a version capable of measuring changes in the magnetic field in three dimensions, for example, for electronic compasses and their use in airplanes, mobile phones, current measurements on a cable, or for Traffic detection.
De esta manera, el sensor puede medir los campos magneticos de los imanes permanentes (por ejemplo, el campo magnetico de la Tierra) y los campos electromagneticos generados por una corriente (CA o CC) en un cable.In this way, the sensor can measure the magnetic fields of permanent magnets (for example, the Earth's magnetic field) and the electromagnetic fields generated by a current (AC or DC) in a cable.
Las figuras 2 y 3 muestran esquematicamente como los sensores (10) que se han desplegado en una carretera, pueden medir los cambios en el campo magnetico de la Tierra cuando un coche pasa por los mismos.Figures 2 and 3 show schematically how the sensors (10) that have been deployed on a road can measure changes in the Earth's magnetic field when a car passes through them.
La figura 4 muestra un ejemplo del registro de un iman en movimiento.Figure 4 shows an example of the registration of a moving magnet.
La invencion se refiere a un sistema que contiene, tanto un sensor "magnetico", como un sensor capaz de detectar los materiales metalicos mediante dos antenas (1x transmisor (TX) y 1x receptor (RX)) que estan normalmente instaladas como una puerta, por ejemplo, en la entrada o la salida de una tienda. El sensor de metales registra todos los tipos de metales de un determinado tamano y volumen. Los sistemas antirrobo conocidos contienen solo un detector de metales, y el fin de esto es registrar el paso de bolsas, mochilas, bolsos o similares que esten aislados/revestidos con, por ejemplo, papel de aluminio. Un inconveniente de tales sistemas es que los carros tambien sean detectados por el sistema, por lo que, en consecuencia, podran ser una fuente de falsas alarmas.The invention relates to a system that contains both a "magnetic" sensor and a sensor capable of detecting metallic materials by means of two antennas (1x transmitter (TX) and 1x receiver (RX)) that are normally installed as a door, for example, at the entrance or exit of a store. The metal sensor records all types of metals of a given size and volume. The known anti-theft systems contain only one metal detector, and the purpose of this is to register the passage of bags, backpacks, bags or the like that are insulated / coated with, for example, aluminum foil. A drawback of such systems is that the cars are also detected by the system, so, consequently, they could be a source of false alarms.
Combinando un sensor magnetico con un sensor capaz de detectar los materiales metalicos, se logra un sistema en el que la unidad de control puede programarse para proporcionar diferentes desviaciones, dependiendo de si es un bolso revestido con aluminio, o un carro que discurre a traves de una zona en la que ambos sensores realizan mediciones. Si es un bolso de este tipo, solo el detector de metal proporcionara desviaciones, mientras que los dos, es decir, el detector de metal y el detector magnetico, proporcionaran desviaciones si pasa un carro de hierro a traves de la zona de deteccion comun de los sensores. Tal y como se ha mencionado anteriormente, el sensor de metales detecta, dependiendo de su configuracion, solo material metalico mas grande que un tamano determinado y, en consecuencia, es posible traspasarlo con un manojo de llaves o con un iman en el bolsillo sin que el sensor de metales lo registre.By combining a magnetic sensor with a sensor capable of detecting metallic materials, a system is achieved in which the control unit can be programmed to provide different deviations, depending on whether it is an aluminum-coated bag, or a car that runs through an area where both sensors make measurements. If it is such a bag, only the metal detector will provide deviations, while the two, that is, the metal detector and the magnetic detector, will provide deviations if an iron carriage passes through the common detection zone of the sensors As mentioned above, the metal sensor detects, depending on its configuration, only metallic material larger than a given size and, consequently, it is possible to transfer it with a bunch of keys or with a magnet in the pocket without The metal sensor records it.
Proporcionando el sistema con una unidad de control adecuada, el sistema puede programarse para emitir alarmas, por ejemplo, solo si se logra un registro de material magnetico, de material metalico no magnetico o de ambos, en un area de medicion compartida (zona de deteccion). Por lo tanto, se logra un sistema que, como mmimo, es capaz de distinguir entre tres situaciones:By providing the system with a suitable control unit, the system can be programmed to issue alarms, for example, only if a record of magnetic material, non-magnetic metal material or both is achieved, in a shared measurement area (detection zone ). Therefore, a system is achieved that, as a minimum, is able to distinguish between three situations:
1. Una bolsa reforzada que esta revestida de, por ejemplo, papel de aluminio, con la que solo el detector de1. A reinforced bag that is lined with, for example, aluminum foil, with which only the detector

metal respondera a la misma;metal will respond to it;
2. Un iman, que solo detectara el sensor magnetico;2. A magnet, which will only detect the magnetic sensor;
3. Un carro, que ambos tipos de sensor registraran.3. A car, which both types of sensor will register.
Normalmente, la unidad de control del sistema sera programada de modo que el sistema no emita una alarma cuando pasen carros por el sistema; es decir, cuando ambos sensores registren un artfculo (situacion 3 anterior).Normally, the system control unit will be programmed so that the system does not issue an alarm when cars pass through the system; that is, when both sensors register an article (situation 3 above).
Las figuras 5A-5D muestran una realizacion de un sistema segun la invencion, por el que pasa una persona que lleva una mochila. El sistema comprende dos antenas (1, 2) instaladas de modo que los clientes tengan que pasar por en medio.Figures 5A-5D show an embodiment of a system according to the invention, through which a person carrying a backpack passes. The system comprises two antennas (1, 2) installed so that customers have to go through the middle.
En cada uno de los dos sistemas de antena (1, 2) hay dispuestos sensores magneticos (3) y sensores de metales (1, 2), respectivamente; sin embargo, en la realizacion mostrada, ninguno de los dos se ilustra con detalle, y los sensores estan dispuestos de modo que tengan un area de medicion coincidente. De esta manera, los dos tipos de sensor registraran cuando entra el carro en la zona de medicion compartida (vease opcionalmente la figura 5B (situacion 3 anterior)) y, tal y como se ha mencionado anteriormente, el sistema normalmente estara configurado para que, en esta situacion, la unidad de control no emita una alarma.In each of the two antenna systems (1, 2) there are arranged magnetic sensors (3) and metal sensors (1, 2), respectively; however, in the embodiment shown, neither is illustrated in detail, and the sensors are arranged so that they have a matching measuring area. In this way, the two types of sensor will register when the car enters the shared measurement zone (see optionally Figure 5B (situation 3 above)) and, as mentioned above, the system will normally be configured so that, In this situation, the control unit does not emit an alarm.
Asf, el sistema registrara que el carro sale del area de medicion (vease opcionalmente la figura 5D), pues el sensor magnetico parara de detectar su presencia, a su vez, solo el detector/sensor de metales registrara la mochila (si esta revestida con, por ejemplo, papel de aluminio) cuando este en el area de medicion, tal y como se muestra en la figura 5D (situacion 1 anterior), y aqrn, la unidad de control ha de emitir una alarma, pues esta presente un objeto de metal/bolsa reforzada.Thus, the system will record that the car leaves the measurement area (see Figure 5D optionally), because the magnetic sensor will stop detecting its presence, in turn, only the metal detector / sensor will register the backpack (if it is covered with , for example, aluminum foil) when in the measuring area, as shown in Figure 5D (situation 1 above), and here, the control unit must issue an alarm, since an object of metal / reinforced bag.
Si, en lugar de una mochila revestida, el cliente porta un iman, la secuencia sera: primero registrar un carro (situacion 3) y despues registrar el material magnetico/iman (situacion 2), y aqrn, la unidad de control ha de emitir una alarma.If, instead of a coated backpack, the customer carries a magnet, the sequence will be: first register a car (situation 3) and then register the magnetic material / magnet (situation 2), and then the control unit must issue an alarm.
Mediante un dispositivo de deteccion/sensor magnetico de tres ejes, es posible calcular un angulo relativo al objeto magnetico en movimiento a traves de la puerta. Esto significa que es posible medir la direccion hacia la que se mueve el objeto magnetico a traves de la puerta.By means of a detection device / three-axis magnetic sensor, it is possible to calculate an angle relative to the moving magnetic object through the door. This means that it is possible to measure the direction in which the magnetic object moves through the door.
Asf mismo, es posible instalar un sensor magnetico de tres ejes en cada antena. Esto proporciona la opcion de calcular el angulo desde cada uno de los sensores magneticos/dispositivos de deteccion con respecto al objeto magnetico, y asf, llevar a cabo una marcacion cruzada. De esta manera, puede determinarse la ubicacion, o incluso la velocidad de un objeto detectado. La unidad de control puede asf mismo estar programada de modo que ignore situaciones en las que la velocidad o la posicion de este objeto se den en un area que sea poco real para un objeto transportado por un cliente.Likewise, it is possible to install a three-axis magnetic sensor on each antenna. This provides the option to calculate the angle from each of the magnetic sensors / detection devices with respect to the magnetic object, and thus, carry out a cross-marking. In this way, the location, or even the speed of a detected object can be determined. The control unit may also be programmed to ignore situations where the speed or position of this object occurs in an area that is unreal for an object carried by a customer.
Combinando la informacion de los dos sistemas de deteccion, es posible configurar un sistema en el que se puede elegir entre diferentes funciones y propiedades.By combining the information of the two detection systems, it is possible to configure a system in which you can choose between different functions and properties.
• Detector de metales sin deteccion magnetica. Este sistema funciona como los sistemas actualmente conocidos.• Metal detector without magnetic detection. This system works like the systems currently known.
• Deteccion magnetica sin deteccion de metales. El sistema esta pensado para los probadores de las tiendas de ropa.• Magnetic detection without metal detection. The system is designed for clothing store testers.
• Deteccion de metales con deteccion magnetica, donde el detector de metal se utiliza para registrar una bolsa revestida con aluminio, y la combinacion se utiliza para registrar el carro, y el sensor magnetico se utiliza para detectar un iman (situacion 2).• Metal detection with magnetic detection, where the metal detector is used to register an aluminum-coated bag, and the combination is used to register the car, and the magnetic sensor is used to detect a magnet (situation 2).
Esta ultima configuracion se puede aprovechar en los probadores de las tiendas de ropa (en los que se sospecha que se retiran las alarmas antirrobo mediante liberadores magneticos trafdos del exterior), y en los que existe un gran flujo de transito de carros y/o cochecitos de bebe.This last configuration can be used in the testers of the clothing stores (in which it is suspected that the burglar alarms are removed by means of magnetic releases brought from outside), and in which there is a large traffic flow of cars and / or strollers Baby
De esta manera, el sistema puede estar configurado de las siguientes formas:In this way, the system can be configured in the following ways:

En la configuracion anterior, tanto el sistema de deteccion de metales como el sistema de deteccion magnetico estan encendidos, y programando el control, el sistema puede, por lo tanto, responder a cualquiera de:In the previous configuration, both the metal detection system and the magnetic detection system are turned on, and by programming the control, the system can therefore respond to any of:
• Bolsas reforzadas, pues proporcionaran informacion inequvoca desde los detectores/sensores, a saber: desviacion positiva para el metal y simultaneamente desviacion negativa para el material magnetico.• Reinforced bags, as they will provide unequal information from the detectors / sensors, namely: positive deviation for the metal and simultaneously negative deviation for the magnetic material.
• Imanes, pues que proporcionaran informacion ineqmvoca de los detectores/sensores, a saber: desviacion positiva para el material magnetico y simultaneamente desviacion negativa para los metales.• Magnets, as they will provide unambiguous information of the detectors / sensors, namely: positive deviation for the magnetic material and simultaneously negative deviation for the metals.
• Bolsas reforzadas con imanes y/o carros de la compra/cochecito de bebe, ya que ambos proporcionan desviaciones positivas para el material magnetico y los metales.• Bags reinforced with magnets and / or shopping carts / strollers, as both provide positive deviations for the magnetic material and metals.
En condiciones normales, el control se programana de forma que, como en los sistemas de la tecnica anterior, la alarma salte con las bolsas reforzadas. Aunque, al contrario que en los sistemas anteriores, es posible, por la presente invencion, proporcionar un sistema que tambien pueda utilizarse para emitir una alarma en el caso de que pasen imanes a traves; y tambien, un sistema que omita la emision de una alarma cuando los carros pasan a traves.Under normal conditions, the control is programmed so that, as in the prior art systems, the alarm will jump with the reinforced bags. Although, unlike in the previous systems, it is possible, by the present invention, to provide a system that can also be used to emit an alarm in the event that magnets pass through; and also, a system that omits the issuance of an alarm when cars pass through.
La invencion no esta limitada a la realizacion mostrada pero se expone en las reivindicaciones.The invention is not limited to the embodiment shown but is set forth in the claims.
